I have DM HD 800 PVR and on page 100 of the user manual I'm doing what it says - entering the 4-digit code...but it flashes after 3 digits are entered - and when I enter 4 digits it doesn't flash at all.
Plazma LG 42PJ350

Basically until I fix this my boyfriend is not going to be able to pay attention to me so it would be very helpful if you have some advice, Ha ha. Seriously.
